DEVICE FOR OPENING AND GUIDING W'EBS 03E CLOTH, 8w.

Application filed Apri1 12, 1916.

To all whom it may concern:

l e it known that I, WiLLARD I. LEWIS, a citizen or the United States, residing at ll al 'pole, in the county of Norfollntltate of Tilassachusetts, have invented a certain new and useful i Improvement in Devices for Gpening and Guiding Webs of Cloth, &c., of which the following is a specification, re'lercnce being had therein to the accompanying drawings.

The invention has relation, generally, to devi s or machinery for handling traveling coz'itinuous webs of cloth and other material. It comprises novel devices applicable for opening or spreading widthwise a web oi? cloth. or the like, straightening out wrinkles and the like, openingout curledover selvages, and automatically guiding the web. Devices embodying the invention are adapted to be employed for opening out and spreading widthwise a web of cloth from the so-called rope-form which it sometimes is caused. to assume in bleaching and other continuous processes, and for guiding it into certain of the machines by which it is operated upon lurther.

T hey are fitted to perform the functions of a scutcher in connection with light and delicate goods which would be injured by the reels, heaters, etc, oi SClllii'llOI'S constituted as usual in practice.

- The invention utilizes the principle or law' that ati'aveling flexible band or the like in moving toward. a revolving pulley or roll. the surface oi which it envelops m tialiy, tends to travel in a direction at rightangles to the axis of revolution of such nilley or roll. Further, it utilizes the said principle to client the opening or spreading of a web widthwise, through the employ ment of ol)liquely-disposed rolls engaging with both surfaces of an extremely narrow marginal. portion of the web, at one or each oi the edges of the latter. General objects of the invention are to bring such principle etlectively into play in accomplishing the special results to which reference has been made.

The invention consists first in apparatus for opening and spreading a traveling web comprising, in combination web-contracting means by which the web is positively held narrowed. width'wise within substantially less than its ormal breadth, a roll or set of rolls revolving upon a forwardly-inclined Specification of Letters Patent.

Patented July 13, 1920.

Serial No. 90,759.

a line extending from the said lateral guidesurface to the roll or rolls, at right-angles to the axis or axes of the latter. Usually, in carrying the invention into effect, rolls are employedin conjunction with both of the margins or selvages of a traveling web. By

utilizing the said principle in connection with both margins of a web the latter is opened and spread widthwise in both directions from the middle toward both margins, and all wrinkles are straightened out from one margin to the other. The action at one margin opposes that at the other, so that through the balancing of the lateral pull in opposite directions the web is maintained in a middle path.

The invention consists secondly in rolls which are arranged. to engage with narrow extreme marginal portions or selvages, only, of the traveling web. More especially it comprises rolls, thus arranged, which are adapted to accommodate themselves to all shifts, outward and inward that happen of the respective margins or selvages due to swaying of the web widthwise, so to maintain such engagement in all of the dirttcrent "positions oi? the veb transversely. Under this p iase oi the invention, the rolls for a given margin or selvage comprise one i or more that are arranged to malre contact with one surface of the web, and one or more that are arranged to make contact with the other surface thereof; Usually, more than two rolls are employed in a group. In order that the web may be held only by narrow marginal portions thereoit, the rolls of one set or" a group are alternated with those of the other set of such group, and in addition the axes of the rolls of one set are inclined'in the direction of their length with respect to those of the cooperating set so that in the dillerent working positions of the two sets of rolls the two planes containing the axes of the respective sets intersect and cross each other. The web-margin is entered into the inner sets, toward the inner ends of the rolls. In

other words, the two sets of rolls are mounted and arranged so that'the place of crossing of the two sets shifts ontwardand inward as the position of. the web-margin changes.

Having reference, to the drawings, and first tov Fig. 1,-- I

From any convenient source, which in some cases will be a suitable container, for instance a truck holding a considerable quantity of cloth in continuous web-form, the web '1 passes toandpartly around an overhead guide-roll 3, around which it changes direction and passes'to and partly around a, feed-roll t havinga frictional surface for engagement with. the web.. The two rolls 3 and 1 are mounted. in any convenient supports (notshown). Feed-roll at is rotated by suitable power connections, and through. its rotation and the engagement of itssurface withthe web it draws the latter from the source of supply to facilitate its P8553526 to and through the devices involved in. the. invention which are arranged in position to act upon the web on its way from 4 the said feed-roll 4; One or more rotating scutcher-reels, as 2,may be employed to act upon the web in\ advance of its arrival at rolls 3, 1, so as to effect a preliminary loosening-up and opening of the web. From roll 'the web passes down to and. partly arounch a guide-roll 3 suitably supported in positionv from which it passes horizontally to the said devices. A pair of feed rolls 5, 6, engaging with the web after it has passed the said devices, operates to draw the web forward past and away. from the latter and advance it to the cloth-handling apparatus by whichthe web is next to be operated upon, the devices in question operating to cause the web to arrive at the said apmargins traveling paratus in a flat open state, laterally expanded and free from wrinkles, with its along predetermined lines. The journals 7 of feed-roll 5 are mounted in bearings (not shown) carried by the fixed frame-work. "Those of feedroll 6 are mounted in bearings provided in connection with arms 9 fixed upon a supporting rock-shaft 10 that is mounted in bearings (not shown) in connection with the fixed framework, the-said rockshaft hav ing an arm 11 carrying a weight 12'acting withv a tendencyto rock the rockshaft and press the feed-roll 6 toward feed-roll 5. The web arriving at these feed-rolls passes under and partly around feed-roll 6, then between the latter and feed-roll 5, and from feed-roll. 5 to the, succeeding cloth-handling apparatus. The particular partsthus far referred to are illustrative, merely, and their. construction, etc., is notinvolved in the invention.

The means for keeping the margins of the web contracted within less than the normal breadth of the web, so that in passing onward. from the said means the latter shall diverge widthwise of the web to the rollsfor site portions of the interior surface of the Y pot-eye constitute guides for the opposite margins of the web, and serve to confine vages, respectively, extend outward in oblique directions to the rolls for opening and spreading the web widthwise, etc. When the web to be operated upon is already in a 'more orless'opened and spread-out state,

other means of confining theweb widthwise within substantially less thanits normal breadth, and providing lateral draft-guides may be employed in practice. r

The rolls are shown in place in. the apparatus inFig. 1, and are shown separately on a larger scale in Figs. 2 and 3. They comprise in this instance two groups B, C, of transversely-extending rolls of small diameter, there being one group for each margin of the web. The number ofrolls comprised in the respective groups mayvary in practice. Figs. 1 and 3 show the inclination of the axes of the rolls of the'difierent groups forwardly in the direction of travel of the v web. It is in consequence of this inclination that, as the web advances, the revolution of the rolls tends to expand the web transversely, in conformity with the principle referred to at the outset herein. As stated above, the rolls of each group are divided into two sets, one thereof comprising those marked 15, 15, etc, and making contact with one face of the web-margin, and the other comprising those marked 16, 16, etc, and making contact with the other face of the said web-margin. The two sets of rolls of a group are supported separately by roll-carriers 17, 17, and the said roll-carriers have capacity for relative movement to permit of such an opening or separation of the two sets of rolls with relation to each other as will allow a web-margin to be entered between the two sets, and to permit of such a closing of the two sets together as will cause the respective sets to engage with opposite surfaces of the web-margin thus entered be tween them. The two sets of rolls are caused to tend to close together upon the said webn'iargin by the tension of actuating springs acting upon the roll-carriers, as explained later herein.

The preferred construction providing for the support of the two sets of rolls of each group, and for the relative movement of the said sets, is as follows :-The rolls of one set are journaled upon one roll-carrier 17, and those of the other set are ournaled upon a similar roll-carrier. Herein, each of the roll-carriers is furnished at itsopposite ones with outwardly-extending ears or lugs 18, 18, which fit upon and are made fast to a shaft 19 located alongside the path of the web and in a plane parallel with the plane of the latter. There are two shafts 19, 19, one for each roilcarrier. The two shafts 19, 19, are parallel with each other, and are mounted in hearings in connection with two pairs of supporting-blocks 20, 20. The supportingbloclts 20, 29, are mounted upon screwthreaded shafts 21., 21, which in turn. are mounted in a. swing frame 22. The said swing-frame is mounted upon suitable supports in conneetion'with the main frame work of the apparatus, as explained later herein.

By mounting the two shafts 19, 19, in hearings in connection with the two pairs of supportirig-blocks 20, 20, the two roll-carriers 1.7, 17, are rendered capable of swinging about the axes of the shafts 19, 19, in a plane intersecting at right-angles the plane of the web, in order thereby to provide for the required relative movement of the two sets'of rolls. It is not necessary in all cases that both sets of rolls should be adapted to swing.

For the application. of the force by which the two sets of'rolls of a group are causedto close together upon the web-margin between them, each roll-carrier 17 is furnished with arms 23, 28, fixed upon the opposite ends of its shaft 19 and extending toward the middle of the width of the apparatus, and contracting spiral springs 24, 241', are provided to act in conjunction with these arms. The tension of these springs, transmitted to the said arms, tends to occasion turning movement of the shafts 19, 19, and. thereby produce swinging movement of the roll-carriers i7, 17, so as to effect the closing together of the two sets of rolls. In order that the tension of the springs may be applied to both of the sets of rolls of a group equally, and in order also that when relative movement of the two sets of rolls with respect to each other talres place both sets of rolls may be caused to move simultaneously either toward each other or apart from each other, the two arms 23,23, at each end of the group of rolls have connected therewith links 27 25, which converge and have their meeting ends joined by a pin 26 working in a slot 27 in an endiiange 22 of the swing fraine 22. The said slot is at right-angles with respect to the adjacent screw-threaded shaft 21, andv is located about midway between the two shafts 19, 19, and their arms 23, 23. The walls of the slot 27 confine and guide the pin, and restrict it to movement along a line at rightangles to the said screw-threaded shaft. '1 he spring 251 located at such end of the group is engaged with the pin 26, and acts through the latter and the two links 25, 25, to applv force equally to both rockshaft arms 23, 20, so as to produce equal pressure of the two sets of rollers against the opposite surfaces of welrmargin in closing them together upon such margin. it is to be observed. that force acting through either or both sets of rolls, tending to rock one or both ri'ill-carriers' in'opoosition to the tension of the springs 24 's, 2st, and transmitted through one or both links at each en d of the roll-earrieii'v arrangement to the pin 26, will operate to move such pin in the direction of the length of the slot against the resistance of the spring. lly reason of the connect in of the pin through the links with both of the rollcarriers, and of theintermediate location of the slot, neither set of rollscan be cruised to swing away from the other set without corresponding movement of the latter, so that movement imparted to the one set will, be transmitted to the other, and the two sets willbe compelled to move simultaneously at thesaine speed to an equal extent in opposite rliiectioiisswitli respect to each other,

As indicated previously herein, engagement of the rolls with narrow extreme marlGO ginal portions or selvages, only, of. the

traveling web is provided for by arranging the rolls of a given group. so that those of the set which engage with. one surface of the web alternate in succession with those ofthe set which engage with the other surface, and

7 each other so that such planes intersect and cross, and by entering the web-margin into the inner angle between the two sets of rolls.

The alternation of the rolls of the two sets is shown in Figs. 1 and 3 of the drawings.

In such figures, as preferred, one of the said sets comprises the first, third, and remaining odd-numbered rolls of the group, these being marked 15, 15, etc., while the. other set comprises the second, fourth, and remaining even-numbered rolls of the group, these being marked 16, 16, etc. The relative inclination is indicated in Figs. 1 and 2. In Figs. 2 and 3'the twov sets of rolls of each group are represented as closed fully under the action of the springs 24, 24, in the ab sence of the web, so that in such views the inner portions of the two roll-carriers 17, 17, of a groupare in immediate contact with each other. When a web is introduced into the apparatus, the inner ends of the two sets of rolls, 15 and 16, of a group are opened or spread apart, which may be done by swinging the roll-carriers oppositely with relation to each other around the axes of the shafts 19, 19, so as to separate the contacting inner portions of the roll-carriers from each other, and the corresponding web-margin is inserted between the inner ends of the two sets of rolls, at the inner side of the place of crossing of the two sets. Then the roll-carriers are freed to the action of the springs 24, 24, which thereupon operate the roll-carriers to close the two sets of rolls together upon the web-margin, as, now, the web is drawn onward through the apparatus, the engagement of the surfaces of its margins with the rolls of the two groups will revolve the rolls upon their individual axes, and by reason of the principle already referred to each margin will work outwardly along the rolls of thecorresponding group until the tendency of either web-margm to move'outward in one direction is counterstantially'less than its normal breadth in advance of the rolls, and by reason of the fact-that the opening and'spreading rolls takeihold of the web only'by itsextreme edge-portions, the draft that is transmitted along a margin or selvage acts between the point at which the latter is nipped by the 'the case may require.

rolls, and the point at which it bends around the lateral guide surface of the web-contracting means which serves as a draft guide, to open and unroll or uncurl curledover selvages.

By reason of the tendency'of the two sets of rollsof a group to. close together upon the corresponding web-margin, the contact of rolls of either set with the web margin at points opposite the spaces of the other set operates to bend the web more or less between and partly around the successive rolls, and to produce frictional engagement between the peripheries of the rolls and the web-margins suilicient for the purposes of the invention. The force which produces the tendency to close the two sets of rolls upon the web acts yieldingly, and in practice is proportioned so as-not to create too strong a pressure of the rolls upon the web. Preferably, a considerable number of rolls is employed in each group, to divide up the pressure and reduce theeXtent to which the web is bent in between the successive rolls of the two sets. V

The angle of relative inclination of the two sets of rolls of a group may be varied, as may be found advisable for securing the best results in practice, by moving the two roll-carrier supporting shafts 19, 19, of such group closer togetheror farther apart, as To this end, each screw-threaded shaft 21 is furnished with a right-hand thread on the portion thereof on which one bearing-block 20 is mounted, and with a left-hand thread on the portion thereof on which the adjacent bearing-block 20 is mounted. hen the shafts21, 21, are rotated by means of the cranlchandles with which they are shown furnished (or by 7' rolls 15, 16, and by providing means for.

varying the angular position of the said swing-frame and the said rolls in a plane parallel with that of the web passing through the roll-system. In this embodiment of the invention, each swing-frame 22 is mounted pivotally, as at 22*, upon a support 30, and is engaged at the point 31 with a collar 32 mounted loosely upon a cross-rod 33, which latter extends at its'ends through slots '34,. 34,'in opposite portions 35, 35, of the fixed framework of the apparatus. Bodily shift of rod 33 within slots 34, 34, serves through collars 32, 32, and their engagement with the two swing-frames 22, 22, to swing the latter simultaneously around their piv ots 22", 22, thereby altering the forward inclinations of the two groups of rolls, and the angle of the longitudinal axes of the rolls of one group with respect to those of the rolls of the other group. This bodily shift of the rod 33 may be effected in various ways in practice. Herein it is provided for by adjustment-devices by means of which both ends of the rod may be adjusted simultaneously. The said adjustment-devices comprise toggle-arrangements which are duplicated at the opposite sides of the apparatus, and means whereby said toggle-arrangements may be bent in unison more or less. The toggle-arrangement at each end consists of two links 36, 37, the first of which is engaged by the outer end thereof with one end of rod 33, While the other is engaged by the outer end thereof with one end of a cross-rod 38 mounted in the portions 35, 35, of the framework, and the meeting ends of the two links are engaged with a nut 39 upon a screw-threaded shaft 40 mounted in a fixed bearing-support 41. Such engagement is provided for in the present instance, as shown in Fig. l, by causing the projecting end of the pivot 36 which connects said meeting ends together, to occupy a slot or groove 39 in the inner side of said nut 39. The said slot or groove is of sufiieient length to allow the pivot-pin freedom for the extent of forward and rearward movement thereof which is incident to the bending of the toggle in effecting adjustments. By turning the screw-threaded shaft 4-0 so as to screw the nut 39 up or down the toggle is actuated so as to shift the rod 33. For the purpose of enabling the two screwthreaded shafts 40, 40, to be turned in unison from either side of the apparatus, each thereof is furnished with a bevel-gear 4'2, and the respectivebevel-gears d2, 42, are engaged by bevel-gears 43, 43, fixed upon opposite ends of a cross-shaft is mounted in hearings in the bearing-supports ll, 41, and provided with hand-wheels 45, i. that are fixed upon the said opposite ends.

Adjustment of the two groups of rolls toward and from each other widthwise of the apparatus, to suit different widths of webs, is provided for by making the supports 30, 30, correspondingly adjustable, and furnishing convenient adjustment means in connection. therewith. For the purposes of the ad justment, the supports 30, 30 are mounted upon the cross-rod 38 and a cross-shaft to that is disposed parallel therewith, by means of lugs fitting said cross-rod and cross-shaft with capacity to slide along such rod and shaft in the direction of the width of the apparatus, and the cross-shaft 46 is furnished with right-hand and left-hand screwthreads upon its opposite end-portions, upon which are fitted nuts 47, 47, engaged in pockets formed in certain of the lugs with which the supports 30, 30, are formed. By taking hold of either of the crank-handles :8, 418, which are fixed upon opposite ends of the screw-threaded adjustment-shaft l6, and rotating the said shaft, the supports 30, 50, and respective groups of rolls may be moved closer together or farther apart, to

suit the Width of the web to be operated upon. 7
